Hello doctor,

My son is 3 months old. He had a cold and cough. Doctor prescribed Phexin syrup 5 ml for three days. But at the medical shop, the pharmacist has given Paraxin 120 ml which I did not crosscheck again with the prescription and gave it to my son. His stools are dark green, and he is very cranky. He cries all the time. Is it because of the medicine? I have stopped giving Paraxin. But would it have caused anything else?



Welcome to

Paraxin contains Chloramphenicol, and it can cause loose motion, vomiting, and abdominal pain. Your baby might be cranky for the same reason. It can lead to other side effects if given in high doses, particularly on blood cell production. Please let me know how many doses you have given? What is the strength of the Syrup? When was the last dose given? As there is no antidote, you need to watch your baby for any change in breathing or change in skin color, abdominal distension, and urination.

I suggest to get your baby physically checked, and get the drug level in the blood if it is available over there, else just get blood lactate levels and other blood tests.

The Probable causes:

Accidentally ingestion of wrong medication.

Investigations to be done:

CBC (complete blood count), CRP (C-reactive protein), serum elctrolytes,
serum lactate.
Serum Chloramphenicol Level.

Differential diagnosis:

Chloramphenicol toxicity.

Probable diagnosis:

Chloramphenicol over dose (toxicity).

Treatment plan:

Watch for breathing, any change in skin color, abdominal distension, refusal of feeding.
Get the blood test done. Get the baby physically checked.

Preventive measures:

Always check for the proper medication before giving it to kids.

Regarding follow up:

Follow up after blood investigation.

Thank you doctor,

I have given 5 ml, twice daily for three days. But as his cold increased yesterday, I gave 5 ml, twice yesterday. I have attached a picture of the syrup bottle. Baby is active, but he has started crying often. I took him to a pediatrician today. He said his breathing is normal. Little congestion is still there. But his voice got hoarse yesterday and today it has become even more hoarse. I hope it is just because of the cold. And the pediatrician asked me to just give nasal drop for his cold and has prescribed Cefixime oral suspension 50 mg, 4 ml, twice daily for four days for his green loose motion. Will this help with his health? Will he recover soon? I am just worried.



Welcome back to

Symptoms you are describing look due to cold and it is usually caused by a viral infection. As your baby is active and feeding well and breathing normally, just use normal saline nasal drops. For loose motions, antibiotic is not required. Feed the baby frequently, and if there is too many loose motions then give Pedilyte ready to drink solution about 25 to 30 ml after each loose motion. For the previous medicine (Paraxin) get the blood test done to be on the safer side but do not worry.
